RELATED APPLICATIONS

This application claims priority to an Australian patent applicationfiled on May 15, 2006, as serial number AU2006902576, entitled “MultiplePay Combination Gaming Apparatus,” which is herein incorporated byreference in its entirety.

TECHNICAL FIELD

The present invention relates to gaming machines, gaming apparatus andto methods of gaming. In particular, the present invention relates to amultiple pay combination gaming apparatus and a method of providing amultiple pay combination gaming apparatus.

BACKGROUND OF THE INVENTION

With the increase of gambling at gaming venues has come increasedcompetition between gaming venues to obtain a larger share of the totalgambling spend. Gaming venue operators have therefore continuouslylooked for new variations and types of games in order to attract bothnew and return customers to their venues.

In response to this need, suppliers of gaming devices and systems haveattempted to provide the sought after variety, while still developinggames that comply with the relevant regulations in the jurisdiction ofthe gaming venue operator. Suppliers of gaming devices therefore arefaced with restrictions on the types of games and gaming apparatus thatare allowable, both in terms of the prevailing regulations and in termsof providing a return on investment to the gaming venue operators.

Originally, gaming machines had physical spinning reels, which werecontrolled by a stepper motor. These gaming machines paid a prize if anoutcome was spun up on a single central pay line that was a winningcombination. Some later machines displayed three positions on each reeland provided three horizontal pay lines, one for each row that could bedefined through the spinning reels.

It is now not uncommon for a player of an electronic gaming machinehaving a video display unit to be able to simultaneously playtwenty-five or more pay lines in each activation of a game. It is usualand desirable to indicate to a player on screen the number of pay linesthat can be purchased and how many pay lines have been purchased in away that allows players to readily compare their purchase with what isavailable.

FIG. 14 shows an exemplary screen shot S8 of a game in which up totwenty-five lines can be played. The available twenty-five lines areindicated by pay line indicators 9. The player has selected to play tenlines and therefore the ten lines that are being played are highlighted.Typically, if a win occurred on one of the pay lines being played, thepay line which displays the winning outcome is highlighted, for exampleby flashing both the symbols in the outcome that meant that it was awinning combination and flashing the corresponding pay line indicator 9.Indication of the winning pay lines is required by the relevant gamingregulations in many jurisdictions.

There is a need or want in the industry for gaming machines to have ahigh number of pay lines, for example machines with 50, 100 or more paylines. However, the higher the number of pay lines that are available,the more difficult it becomes to clearly display the pay lines onscreen. In addition to providing information that allows a player toplay the game in an informed way, a game designer or gaming machiningmanufacturer must overcome the problem of presenting the game in anattractive way.

FIGS. 5 to 10 show exemplary screen shots S1 to S6 of a game 16 inaccordance with one embodiment of the present invention. The game may beimplemented by the gaming machine 10, gaming apparatus 100 and/or withinthe gaming system 200, with a game controller 101 causing a display 106to display the screen shots S1 to S6 during game play. Unlessspecifically stating otherwise, the following description refers toimplementation of the game on a standalone gaming machine 10 (see FIG.1).

The game 16 is a spinning reel type game. Five spinning reels 1-5 areprovided, each of which displays four playing elements or symbols 6 (oneonly indicated by a reference numeral). The symbols therefore define amatrix of five columns and four rows. If the game 16 pays from left toright, as is typical of a spinning reel game, up to 1024 differentoutcomes can be defined in the matrix, representing every possiblecombination of visible symbols, with each combination having one symbolfrom each of the five reels 1 to 5.

In the exemplary game 16 shown in FIGS. 5 to 10, a wager indicator 40shows five combinations, indicated by combination indicators 41-45. Eachcombination indicator 41-45 shows the number of outcomes or pay linesthat are included in that combination. In the example shown, theavailable combinations allow two, twenty, fifty, eighty or one hundredlines to be purchased by a player. FIG. 5 shows a screen shot S1 whentwo lines have been purchased, FIG. 6 shows a screen shot S2 when twentylines have been purchased and so forth for FIGS. 7 to 9. As is usual ina gaming machine, during normal play and excluding from considerationany “scatter pays” or other special symbols or features that may beprovided, only a winning combination that occurs on a purchased pay lineresults in the award of a prize in credits or another award.

FIGS. 5 to 10 show an embodiment of the present invention in which allfive combination indicators 41-45 are displayed on screen and theselected combination is highlighted. In less preferred embodiments, thedisplay may only show the combination indicator 41-45 that correspondsto the combination selected by the player. For example, in FIG. 5 onlythe combination 41 showing “2” lines may be displayed and in FIG. 8 onlythe combination 44 showing “80” lines may be displayed.

The wager indicator 40 can be viewed as a representation of a gauge,which gives a graphical representation of the proportion of outcomespurchased relative to the total number of outcomes available to bepurchased. The gauge starts at the top of the screen (FIG. 5) when theminimum number of outcomes has been purchased and progresses towards thebottom of the screen (FIG. 9) when all possible outcomes have beenpurchased. Although the gauge shown in FIGS. 5 to 10 shows discrete tabsfor each combination indicator 41-45, this is not essential and thegauge may appear more like a temperature gauge, optionally changingcolour dependent on the number of outcomes purchased and optionally onlydisplaying an integer that indicates the number of outcomes purchased.

Therefore, in accordance with the instructions of the game 16, the gamecontroller 101 causes the display 14 to show indicia of the number ofoutcomes purchased without the complexity and clutter of displayingevery outcome that is available to be purchased. In addition, the screenpreferably also graphically displays a representation of the proportionof outcomes purchased relative to the total number available to bepurchased. This can be a general indication of proportion rather than anexact or close approximation of the actual proportion, as is the casewith the example provided in FIGS. 5 to 10.

The bank of buttons 22 or other user interface 107, which may includethe touch screen 106A, preferably has a button or other selectorcorresponding to each of the five combinations. Alternatively, a singlebutton may be used to cycle through the five available options, or twobuttons provided, one to move to the next highest option and the otherto move to the next lowest option. In one embodiment, a player of thegaming machine 10 could touch the touch screen and drag his or herfinger along the combination indicator 40 or other gauge, with thenumber of pay lines increasing or decreasing as the player moves alongthe combination indicator. The gaming machine 10 would display anincreasing or decreasing wager amount in a bet indicator 48 (see FIG.10) as the number of pay lines selected for purchase increase ordecrease respectively.

In an alternative game, the player may be able to select many morecombinations of outcomes. For example, for a game having five spinningreels and three symbols from each reels displayed for each gameactivation the player may be able to choose between 1 and 1024 lines. Inthis case, the bank of buttons 22 or other user interface 107 may havean “increase bet” button and a “decrease bet” button. The wagerindicator 40 when displayed as a gauge may then also have a much higherresolution of steps and could show a moving marker as the player pressedthe “increase bet” and “decrease bet” buttons.

FIG. 10 shows a screen shot S6 following the purchase of eighty paylines and play of the game 16. The result of the game is that one of thepurchased outcomes, the thirty-eighth pay line is a winning combination.Having purchased eighty lines, as indicated by the highlighting ofcombination 44 in the wager indicator 40, at a cost of 40 credits ($0.40in a 1 cent game) as indicated on the screen under the “BET” heading, awin of 8 credits resulted, as indicated on the screen under the “WIN”heading. The win of 8 credits would typically be stored by the gamecontroller 101 in a software implemented win meter, and then transferredto the credit meter of the gaming apparatus after any subsequent eventsthat may be provided as part of the game.

An outcome indicator 46 indicates the pay line that caused the win. Nooutcome indicator 46 is displayed for any pay line that did not containa winning combination. Multiple outcome indicators 46 may be displayedsequentially or simultaneously if more than one pay line contained awinning combination that contributed to the win meter under the gamerules. In the embodiment shown, the outcome indicator 46 includes anumber identifying the pay line and also a representation of a pay line46A showing the symbols that made up the pay line. These symbols mayalso flash or otherwise be highlighted to the player.

The arrangement of the outcomes, in this example pay lines may be variedto match the wager indicator 40. Traditionally, the pay line allocatedto pay line number one is a straight pay line that traverses through thecentre row of the symbols defined by the displayed part of the spinningreels. In the currently contemplated preferred embodiment the pay lineallocated to pay line number one is located towards the top of thescreen to match the location of the combination indicator 41. The first50 pay lines may be predominantly defined by symbols in the upper tworows and the second 50 pay lines may be predominantly defined by symbolsin the lower two rows. In one embodiment, the first symbol or leftmostsymbol in a game that pays left to right across the spinning reels, isdominant, so that the first 50 pay lines are defined by patterns wherethe symbol on the first reel is predominantly on the upper two rows.Similarly, for the second 50 pay lines the symbol used on the first reelmay be predominantly located on the lower two rows.

FIG. 11 shows a possible arrangement of lines in accordance with thisarrangement method. In this arrangement the first 50 pay lines,specifically pay line 1 to pay line 50 all have the first symbolposition in one of the top two rows of the first column/reel. Theselines also have the last symbol position in the same row of the lastcolumn/reel. Similarly, the last 50 pay lines have first and last symbolpositions in the lower two rows of the first and last columns/reelsrespectively.

FIG. 12 shows all 100 of the outcome indicators 46 for the gamedescribed herein in relation to FIGS. 5 to 11. When an outcome displaysa winning combination of symbols, the outcome indicator 46 for thatoutcome is displayed between the wager indicator 40 and the symbols inthe position horizontally in line to the position of the outcomeindicator 46 shown in FIG. 12. For example, the outcome indicator ‘3’would be displayed between the wager indicator 40 and the symbols wherethe outcome indicator ‘1’ is currently shown. Similarly, the outcomeindicator ‘42’ would be displayed where the outcome indicator ‘40’ iscurrently shown.

In the example game shown in FIG. 10, the player wagered one credit perline-cost. The game may provide the option to wager two or more creditsper line cost. For example, if the player played eighty lines at twocredits per line cost and game outcomes of FIG. 10 resulted, the betwould have been eighty credits and the win sixteen credits. The playercould vary the credits per line cost using the bank of buttons 22.

FIG. 13 shows an example screen shot S7 in which the credits perline-cost are also displayed as a gauge. In screen shot S7 the wagerindicator 40A is similar to that previously described and a perline-cost indicator 47 shows the bets per line, the options being 1, 10,24, 40 (currently selected) and 50 in the example shown.

In one embodiment of the invention, where a player has purchased lessthan the maximum number of outcomes and one or more winning combinationsoccurred in outcomes that were not purchased, then the gaming apparatusmay indicate this to the player. For example, if the player purchased 20lines in a game supporting up to 100 lines, winning combinations inlines 21 to 100 may be indicated. Preferably the indication is in a lessprominent way than for winning combinations that occur in outcomes thathave been purchased.
